I didn't try that updated version yet, but I'm afraid I discovered
some problem. I've switched from my Denon 1912 to the older Onkyo
TX-SR605 and there is problem with multichannel playback. I've tried:
> speaker-test -D hdmi:CARD=Generic,DEV=0 -c6 -r192000 -F S16_LE

speaker-test 1.0.25

Playback device is hdmi:CARD=Generic,DEV=0
Stream parameters are 192000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Rate set to 192000Hz (requested 192000Hz)
Buffer size range from 64 to 87360
Period size range from 32 to 43680
Using max buffer size 87360
Periods = 4
was set period_size = 17472
was set buffer_size = 87360
0 - Front Left
4 - Center
1 - Front Right
3 - Rear Right
2 - Rear Left
5 - LFE
Time per period = 17.027360

But I can hear sound for rear right and rear left only :(

Is there anything more I can provide to help resolve this? Do you have
any idea how we can resolve this?

After some testing I found out that xbmc works very nice :)
